Hilary Duff Has Girls Night Out with Nicole Richie at Husband Matthew Koma’s Los Angeles Concert

The actress and reality TV star stepped out on Saturday night as Duff’s husband’s band, Winnetka Bowling League, held a show at West Hollywood's Troubadour

Hilary Duff and Nicole Richie stepped out for a fun girls night in Los Angeles this weekend.

The actress, 36, and reality TV star, 42, were spotted at the Troubadour in West Hollywood on Saturday, June 29, where the former’s husband, Matthew Koma, and his band, Winnetka Bowling League, played a concert. Photographers caught the wives of rockstars (Richie is married to Good Charlotte frontman Joel Madden) holding hands as they exited the building together.

Duff was seen in a sheer blue oversized button-up, loose black pants and boots, with her hair pulled back in a neat bun. Meanwhile, Richie, sported a strapless black corset bodysuit with blue jeans and black boots, as her loose blonde curls flowed.

Per the Daily Mail, music producer Josh Abraham posted a group photo with Duff, Richie and their husbands standing behind with their arms wrapped around their waists to his Instagram Stories. He simply captioned it, “Date night.”

Koma and Winnetka Bowling League’s L.A. show was part of their ongoing headlining tour, which kicked off in Seattle on Wednesday, June 25. The alt-rock trio — which includes Koma’s brother Kris Mazzarisi and Sam Beresford — has their next concert in Denver on Tuesday, July 2, before more scheduled tour stops in Chicago, Nashville, Atlanta, Washington, and New York this month. The band will conclude their North American run in Charlotte on Friday, Oct. 4.

Winnetka Bowling League’s tour follows the Friday, May 31 release of their debut album, Sha La La, which Koma previously told PEOPLE is a collection of songs that captures his experience in his 20s.

“It just feels a little bit more like we're able to say, ‘OK, we've arrived at the identity of this thing,’ which is cool,” the 37-year-old musician said of his band’s alternative project. “It feels really good to have a body that's a bit bigger and feels like there's a bit more for you to be able to dig your teeth into.”

While Koma does get candid about his life on the album, he shared that he’s not quite ready to write about his wife Duff and their three daughters.

“I'm not really ready, or I don't think I'll ever be hungry to relate to an audience on fatherhood or being a great husband,” he admitted. “Those just aren't the songs that I've ever heard and been like, ‘I want to listen to that again and again,’ and I don't really care to share that part.”
